Abstract A facilesynthesis of 2-substituted benzo[b]thiophen-3-ols in a simple reaction system is reported with water as the only media. Density functional theory (DFT) investigations suggest two pathways comparable in energetics: A neutral pathway with concerted C-C bond formation and hydrogen transfer and an anionic pathway with anion attack to the carbonyl group. Studies indicate that water plays
